7K RPM's ... Oops! Rev Limiter ???

I said my plan wasn't to rev it more than 6k, and you disagreed !! :eek: That is neither an "agree nor disagree" statement because it was my plan LOL
No need to rev any engine past the point of making power, other than to make noise
.
Maybe change your cam or cam timing. You have the heads and intake and carb already. Don't be afraid to just stick your foot in it.
An that is not noise at 7000 that the beginning of the sb music to the ears. 7500 is even better.
